First of all i would consider having a car in this city as a drawback more than as a plus unless you live far away or you have family in with case you would probably need it but he is alone i don't think a car in this city add any value to your life standar it will add a stress but i supose depend on the person i don't like the idea of having a car in this city anyway, second 2 k between pharmacy and medical insurance lol really? what are you 90 years old, i barely use if i use more than 100 pesos in a given month and normally the medical plan my company pays make that ammount even smaller in pharmacy at my age and medical insurance is not needed as one of the working benefit that your company will pay for you is a more than adecuate medical insurance for you, and as he mention he is going to work in here.
Anyway i agree with the rest of the expenses, the rent depend on if he want to live alone or he want to share a department (that depend on how social you are and how you like to live, alone or live with other people), but i supose the diference in perception come with our diference of age here, what is well for me even when i consider that i live prety well and travel abroad a lot, probably is not that well for you at your age, and the use and expenses depend as well alot on your given age and if you have or not family.
I'd like to see the break down of your expenses if you are earning ~12k per month and traveling abroad a lot. That may have been true 3 years ago, but I don't buy it in today's economic climate.
